I will admit, I'm 16 and still find Teen Titans to be highly entertaining as a tv show, and I was secretly hoping they would make a game based on it because I saw potential. I was hoping for a fun game that takes advantage of their wacky personalities, and also use of each of the five Titans special powers. Luckily, my hopes were answered very well with this game for the Game Boy Advance.
You start off with the Hive busting into the Titan Tower, and after you chase them off you are left to wonder what they were doing there in the first place. But shortly after you realize that they have actually cloned your titans, leaving you to fight these replicas. Enemies are never hard, but rather a fun challenge. Take Jinx for example. She has the ability to drain your life and give restore hers, as well as messing up your controll pad, making you walk backwards instead of forwards and etc. However, like I said, it's never too hard, just fun.
And as I hoped, you can change you characters on the fly just by holding the L button and selecting your titans. Also, a nice bonus is that your titans don't share health meters (meaning that if Starfire is almosts dead, then you can switch to Beastboy and start anew with full health while Starfire's stays low.) Plus, your enemies will be colored, which indicates their weakness. So, if an enemy is yellow, you should switch to Starfire and they will die easier, blue for Cyborg, Red for Robin, etc. And this all in all equals up to a fun, colorful game.
However, there are reasons I knocked it down a few stars. Playability is solid... however, since this is the GBA combos are VERY limited. And after a while you find yourself just doing the same moves over and over again. Also, is it just me, or is there a dominant color in the game? For me, I constantly found myself with yellow enemies, making me use Starfire throughout a lot of the level, which also meant her health inconviently stayed low throughout most of the levels. But that was the only playability flaw, which is very minor making it potential to be a GREAT game series.
My only other nag is that the game is so short. A mere 6 levels really is hardly worth 30 dollars. But still, each of the six levels are fun, colorful, with fun bosses. So all in all, the game can keep anyone entertained (well, anyone who doesn't automatically write off Teen Titans as a childish kiddie game.) And it is definately worth your time if your a fan of the series.
